Gut Health & Allergies: Why Your Symptoms May Be Starting in Your Gut
By Dee Davidson, FDN-P
If spring rolls around and you find yourself reaching for tissues, eye drops, or antihistamines… you’re not alone.
What if I told you that your allergies may not actually start with pollen?
What if they start in your gut?
The Gut–Immune System Connection
About 70% of your immune system lives in your gut.
That means your gut isn’t just responsible for digestion and it’s constantly:
Communicating with your immune system
Deciding what is safe vs. harmful
Regulating inflammation
When your gut is balanced, your immune system can respond appropriately.
When it’s not… the body can start to overreact.
That’s where allergies come in.
Why Allergies Are Often a Gut Issue
Allergies are essentially an overactive immune response.
Instead of calmly responding to something like pollen, dust, or certain foods, your immune system reacts as if it’s under threat.
Why does this happen?
Because the gut may be:
Imbalanced (good vs. bad bacteria)
Inflamed
Permeable (“leaky gut”)
Overloaded with toxins or stress
When the gut barrier is compromised, your immune system becomes more reactive—and that can show up as:
Seasonal allergies
Food sensitivities
Skin issues
Chronic inflammation
The Missing Piece: Testing, Not Guessing
This is where I see so many people get stuck.
They try:
Eliminating random foods
Taking supplements
Managing symptoms
But without understanding what’s actually happening in the gut, it’s still guessing.
Why I Recommend a GI Stool Test
A GI stool test is one of the most valuable tools to truly understand your gut health.
It gives us insight into:
Bacterial balance (good vs. bad bacteria)
Immune markers (how your gut immune system is functioning)
Inflammation levels in the colon
Yeast, parasites, or overgrowths
Digestive function (how well you’re breaking down food)
Gut lining integrity
This allows us to move from:
guessing → to targeted, personalized support
Strengthening Your Gut = Supporting Your Immune System
When we improve gut health, we’re not just improving digestion—we’re:
Regulating immune responses
Reducing inflammation
Improving resilience to environmental triggers
Supporting hormone balance
Increasing overall energy and well-being
This is why many clients notice improvements not just in allergies—but in:
Skin
Mood
Energy
Weight
Hormones
Dee Davidson's Insight
Allergies aren’t just something you “have to live with”
They’re often a signal that your immune system needs support—and your gut is where that starts
